Subject: [Exim] temporarily unable to verify sender address (??)
Hi,

exim-tls version 3.35

I wonder if someone can tell me what the errormessage in the subject
really means. Take a look at this:

| [0:00] [root@knopje:/home/ssmeenk] # nc dot 25
| 220 dot.freshdot.net ESMTP All Your Mail Are Belong To Us
| HELO knopje.freshdot.net
| 250 dot.freshdot.net Hello knopje.freshdot.net [195.64.83.23]
| MAIL FROM:<root@???>
| 451 rejected: temporarily unable to verify sender address
|               (try again later) <root@???>
| QUIT
| 221 dot.freshdot.net closing connection


But if specify a user as the sender:

| [0:01] [root@knopje:/home/ssmeenk] # nc dot 25
| 220 dot.freshdot.net ESMTP All Your Mail Are Belong To Us
| HELO knopje.freshdot.net
| 250 dot.freshdot.net Hello knopje.freshdot.net [195.64.83.23]
| MAIL FROM:<ssmeenk@???>
| 250 <ssmeenk@???> is syntactically correct
| QUIT
| 221 dot.freshdot.net closing connection


the command was accepted!

What I want to do is create a situation in which my home-machine can
send out email via my co-located machine by authenticated SMTP and TLS.
I have the authentication and TLS part set up correctly, but then this
happens...

Also, how do I tell my exim on my home machine that mail to
users @ 'knopje.freshdot.net' needs te be delivered locally, and
mail to users @ '<whatelse>' needs to go through my smarthost (dot),
but all outgoing mail must have @freshdot.net as sender... I must say I
haven't really tried fixin this, but if someone could copy-paste
something, it would save me time...
